Nice effort, Sir ji...
EGARLY WAITING FOR 3RD PART
3rd part is also there please check
Nice video sir ji 🙏
This topology is slightly different then a typical half bridge topology. this kind of capacitor won't charge with DC therefore they do not act as voltage divider, c1 c2 provides path for the alternative poultry means if low side switch conduct, c1 provides path for the positive. if High side switch conduct c2 provides path for negative.👍
🙏🙏🙌🙌
It is found very useful technical informative video, thanks for sharing 👍, now kindly explain about 40N60 and 40T60, how to know the gate circuit in blust condition in a defective inverter welding machine, kindly explain in detail, Stay blessed
Thanks
Sir fishing inverter working video banan.
Great
Mast ha boss
Sir aap ne capacitor bank ki value galat batai hai. Welding machine ka capacitor bank karib 1000 uf tak hota hai. Aap Violet colour ki pulse ko pink bata rahe hai. Q1 & Q2 ke across jo rc snubber laga hai wo transformer ke primary ke acros lagta hai. But it's a great effort you've made. Thanks.
This is half bridge configuration. Please read the topology,...,... thanks for your comment
@@scienceinnovativebrain in your first part you've shown the value of four caps that is 470uf each, and in the 2nd video you are saying it to be 5-10uf, we don't expect this type of silly mistakes from you at least.
@@rmjnm dear viewer please understand the topology and configuration of inverter in first video capacitors are DC bank in 2 video half bridge technology using 2 IGBT and 2 capacitors that less value capacitor will discharge its energy in transformer primary coil in first cycle and in 2nd cycle other capacitor will discharge and 1st capacitor will charge by dc bank. And this process is happening for each cycle of operation. Pls understand the topology and configuration and process
Well explained

Bahut accha sir, Sir screen shot ke liye thoda board se hat jaiye ga.
Sir ji, jis prakar hum log Mosfet bali machine ka drive volt check karte hain, usi prakar IGBT machine ka Gate volt kaise check karen.
Circuit diagram me bata k samhaju kyo ki practical dekha na aasan nhi hai Next video bana dunga
Abhi aak 3 phase welding machine ka video dekh k samajiye English version uploaded hai Hindi version gping to upload.

Sir g ,
Single card welding machine me jo LNK626PG lga hota hai , Iska function samjhha den ,
Sir kuch component jase 47R,1nf, 2 kV ko circuit me Kya role ka plz bataye.
That are snubber circuits to protect IGBT or mosfet
Thank you. Concept is so clear now. Specially the gate turn on and off resistor section. Need help regarding 4612 8 pin mosfet ic for igbt drive. Ic gets short in 5 sec at power on.. Then smps goes dead due to short ic. Igbt and surrounding resistors r ok. Please guide. Don't hv oscilloscope
You send me pictures on my telegram
t.me/sunsemoon
It will depend how the ckt connected and this is u are using to drive other igbt check first that igbt are ok or not also check the power supply given to this ic also the input trigeer to this ic if both are turning on at a time then it will short the power supply and ic will burn in few seconds
You can send the circuit on my telegram
@@scienceinnovativebrain sir, please explain...why you have connected RC circuit across the IGBT .
@@bhuwanextrovert6799 to protect igbt from spike during the switching operation.

Sir welding machin me 2 variabal hote hai 1hota ampiar ko kam jyada karne ke liye 2 hota force ka variabal force ke variabal se voltage kam jiyada hota hai kya curcuit expaen
Yes
Ye force ko electrical me voltage bolte hai isko control system me analogy conversion bolte hai

Hello Sir I have a question can you please answer me...
may i choose igbt based arc welding machine machine as a continuous power supply ??
A welding machine is not a continuous power supply since it's cooling is not proper for IGBTs and transformer . Even welding is doings in pulse duration some time on sometime off.
So, can you tell me how we can convert the arc welding machine to a continuous power supply..
How much current and voltage rating of your welding machine, and how much continuous dc current and voltage you required.
Welding machin force variabal me kya curcuit explen
Means
Igbt ka set kitna jora laga sakta?
Wo depend Karega Ki igbt ko proper trigger current supply kr sake uska driver transformer or circuit
200amp welding machine
I g b t ok. Out put voltage. 62V
Welding is low.
Please help me sir
Check the current setting pot and feedback loop part
IGBT Driver tx kharab hone ki condition ka ek video banabe, either with the help of DMM or DSO.
Sir 3phase base igbt welding machine circuit diagram bataye
I have made 3 phase IGBT based welding machine video in Hindi and English both languages with circuit diagram please check in my videos
Q1 Q2 KE PERAL ME R C LAGA HE ESKA KYA ROL HE ISKA VALUE KASE NIKALE PL. BATAYE
Igbt gate me 4.7nf capacitor is calculation kya he sir?
Sir mai kaafi preshaan hu or pure RUclips pr vdo dhundh chuka hu lekin mujhe smjh nhi a rha h ki igbt pr drive pulse a rhi h ye kaise check or drive pulse ac kyu aa rhi h jbki mai jb inverter repair krta hu to usme gate pr 3.-4.12vdc ke pass aate h ,
Or sir ek baar inverter me mosfet short hone ke baad hme pura drive section repair krna pdta h to, isme kaise drive check kre ki sahi h ya nai wrna lagate hi igbt fir short ho jayenge
Sir please help ..aapse umeed lagi isiliye comment kiya
Kya aapke pass isolated oscilloscope hai uski hi help se drive pulse check kar sakte hai. Naya MOSFET lagane se pahle high voltage dc supply OFf karke
1. sabhi gate drive pulse check kr lo a rhi hai ya nhi
2. Complimentary pulse k beech me deat time kitna aarha hai. 1.2us sec ya jayada hona chahiye per depend karega kitni frequency per chal rha hai
Sir, ye igbt 40n60 bar bar blast he,amp increase time kiya problem he,please solve
Problems Thoda sahi Se explain kariye. Kam load current per sahi se chal rha hai kya thoda detail me bataiye problem kya ho that hai
@@dn7918 kitna input voltage de rhe hai
Aur main kun sa part blast ho rha hai
Agaer capacitor jayada voltage per chager ho gya to bhi problem hai.
Load current kitna khiich rha hai welding machine,
Ya current wala protection kaam nhi kr rha hai.
Driver transformer deatail not foun input voltage and output voltage of driver transformer
Sir 3plt machine.24 volt o de rakha ha.but rely on nahi ho raha ha.Ptc hit ho jarahai.
Relay ko 1 sec k under hi on kr do nhi to ptc jal jayega. Relay ko check kro khrab nhi hai na. Ya 24dc koi ko nhi ja rha hoga

Output voltage kis pe depend he??? Mera do igbt machine he ek ka output voltage 55v he aur ek ka 78..dono me same 4 igbt he.. ?
Transomer ratio per and output close loop feedback voltage to Pwm ic
@@scienceinnovativebrain frequency se voltage change to sakta he na sir?
@@scienceinnovativebrain thank you
गेट drive trasformer ko puls kaha se milta hai, jo dono IGBT ko baari baari se on karta hai
Next part ke next part me samjhaunga jam pwn ic ka video lecture banaunga
Sir, kya koi esi bhee configuration hoti hai jisme drive transformer ke secondaries ke dots similar side me ho? ese to dono MOSFET ON ho jayenge ikathe??
Yes hota hai but mosfet ek hi leg me nhi lga hota hai dusre leg me lga hoga H bridge ke
@@scienceinnovativebrain Sir me circuit bheju apke email per ya whatsapp per?
@@scienceinnovativebrain sir mera wala half bridge hai
Can i set H20R1203 ?
This is 20 amp igbt 1200v you can use but it will depent how much output current in transformer secondary then calculate primary current that is igbt wirking current based on that only igbt current will decide. Or have to use parallel igbt to increa current
How friquency need for this diagram? How Hz send in get poit?
Aur sir mere paas ek welding machne hai jo ki on condition me hai par jaise hi welding hota hai welding nahi ho pata hai dusari baat ki aadha rodh jalta hai bhich me output chhodh deta hai machine chalu rahti hai
Check looes connection or may be igbt temp is increasing

350 dc to 220 ac inverter मे गेट डिस्चार्ज रजिस्टर 10k का लगा हुआ है और गेट on रजिस्टर 10 ओम का है जिसमें 60 वोल्ट dc इनपुट तक तो सही काम कर ता है लेकिन इससे उपर वोल्टेज पर igbt ब्लास्ट हो जाती है इसके पीछे क्या कारण हो सकता है क्या गेट डिस्चार्ज रजिस्टर की वैल्यू कम की जाए या कोई capacitor इस रजिस्टर के perellol मे लगाया जाए जेसे आपने video मे बताता है हालाकि मेरे वाला circuit egs002 module पर आधारित है
Kis configuration me laga hai ckt aur kya bina load me hi ud rha hai ya load k sath
